Title: Hydrostatic gear machine
Inventor: BAUM HEINZ
IPC: F04C15/00
Filed: 1985-10-12
Abstract: Hydrostatic gear machine, preferably gear pump, the drive shaft of which is arranged in axially and radially loadable rolling bearings and, via a coupling, has a torque connection to a drive bar present in the attachment bearing. The object and aim of the invention consist in the continuous lubrication of the attachment bearing, including coupling, in the low-pressure range, to guarantee long life and low conveying flow losses. According to the invention, this aim is achieved by the low-pressure side of the gear machine having, via an axial recess of the bearing body and an adjoining duct in the cover of the attachment bearing, a liquid connection to the interior of this cover, which receives rolling bearings and sleeve for bearing the drive bar and/or for torque transmission from the latter to the drive shaft. Furthermore, via a recess of the cover in the passage region of the drive shaft and via the bearing gap of the same in the bearing body, the lubricating circuit with the low-pressure side is closed. The area of application of the invention is hydrostatic gear machines with an attachment bearing, which can be used as a pump or an engine.   <IMAGE>
Patent DE-3540354-A1 (DE)
Title: Coupling device
Inventor: HEHL KARL
IPC: B29C45/17
Filed: 1985-11-14
Abstract: The coupling device for coupling an injection mould transported laterally during mould change comprises hook-in elements (24a; 25a) on the piston rod (24) of a driving piston-cylinder unit and on the injection mould (18). The hook-in elements (24a; 25a) hook into one another in the course of the transverse transport of the injection mould (18) in an asymmetric coupling space (35) disposed within the injection mould (18). The coupling hooking-in is achieved, without interrupting the transverse transport of the injection mould (18), by means of a control device (30, 31) by means of which the speeds of the piston rod (24) and injection mould (18) can be matched to one another. However, the coupling hooking-in can also be achieved in that the coupling space (35) opens freely into the lateral wall of the body of the injection mould (18) and the piston rod (24), in its rear starting position, terminates within the coupling space (35') (Fig. 3). <IMAGE>

Title: Roof covering consisting of a flexible material
Inventor: KORTHAUS RICHARD
IPC: E04D5/10
Filed: 1986-03-27
Abstract: The invention relates to a roof covering consisting of a flexible material, that is to say webs which are delivered in roll form and comprise substrates which are impregnated or coated with bituminous sealing compositions and are in the form of sheets or similar two-dimensional structures. In order, in the case of said roof covering, on the one hand to provide a very cost-effective means of preventing the neighbouring layers from sticking together when rolled up and, on the other hand, to ensure effective protection against the roof covering being ruined in friction zones after laying, the invention proposes that at least one of the two outer surfaces of the web be coated with a wax-like layer, in particular that the outer layer which is at the bottom in the used position has the wax-type layer. <IMAGE>

Patent DE-3618691-A1 (DE)
Title: Method for the adjustment of an optimum brake slip
Inventor: KOST FRIEDRICH DIPL ING
IPC: B60T8/1763
Filed: 1986-06-04
Abstract: The aim of this concept is to adjust the brake slip in controlled braking of a vehicle wheel to a value at which, on the one hand the coefficient of adhesion  mu  in the longitudinal direction is close to the maximum value attainable and, on the other, an adequate coefficient of adhesion is available in a transverse direction. This slip value lies below the value at which the coefficient of adhesion in the longitudinal direction reaches a maximum. Whereas the brake slip curve  mu ( lambda ) has a zero gradient at the maximum coefficient of adhesion in the longitudinal direction, at the slip value to be set  mu ( lambda ) assumes positive gradients. In addition to the advantage of higher cornering forces, the concept presented offers the facility for purposely limiting the yaw moments acting on the vehicle in controlled braking and thereby of improving the controllability of the vehicle.

Patent DE-3627835-A1 (DE)
Title: Telescopic profiled sail
Inventor: DEBOR WILHELM
IPC: B63H9/06
Filed: 1986-08-16
Abstract: Telescopic profiled sail for propelling watercraft by utilising the wind energy in the form of a profiled wing which is fastened to the watercraft in a perpendicular position. The profiled wing is of telescopic design, as a result of which the effective sail area is increased by extension or reduced by retraction. In the retracted state, the profiled wing can be lowered by a lift into a silo, as a result of which it disappears entirely below the deck of the vessel. By lifting to deck level and locking the support frame to the deck construction, the profiled wing is made ready for use again and can be extended for sailing. The profiled wing is rotatably mounted on the support frame and can be rotated about a vertical axis and secured at any angle.
Patent DE-3629813-A1 (DE)
Inventor: BREME JUERGEN
IPC: A61F2/02
Filed: 1986-09-02
Abstract: Wire-type surface structures on the anchoring parts of implants made of special steels and cobalt-chromium-molybdenum alloys have already been proposed. These are intended to improve the functional loading capacity of the implants. A secure growth of bone tissue onto compact titanium implants with a smooth or even a rough surface structure has also already been observed. However, the production of wire-type surface structures on titanium implants has hitherto only been possible, if at all, with an economically unacceptable outlay. According to the invention, a method is proposed in which a main body made of titanium is covered with a compact netting of titanium and iron wires, this netting is secured to the main body, for example by welding or pressure welding, and the iron is then selectively dissolved out by means of an oxidating acid to which titanium is resistant.
Patent DE-3630957-A1 (DE)
Title: Rotating shears with speed control device allocated to their drive device
Inventor: HABERKAMM KLAUS-DIETER
IPC: B23D36/00
Filed: 1986-09-11
Abstract: A drive device, equipped with a speed control device, of rotating shears, in particular crank-type shears, is to be operated in such a way that reactions from a cut on the feed rate of the material to be cut are eliminated and tensile and/or compressive stresses in the material to be cut between the shears and a roll stand are prevented.   This is achieved by a command-variable generator 19 being arranged upstream of the control device 18 of the drives 14, 15. When the drives are run up, the command-variable generator 19 brings about a derivative action which exceeds the speed value to be regulated and is also maintained beyond the start of cutting and then bends spontaneously onto a transition curve which conforms steeply and asymptotically to a compensation curve which controls the angular velocity of the drive in accordance with the geometry provided during the drive of the blade carrier in such a way that a constant horizontal speed is achieved in the cutting area. This curve then merges into the delay curve for returning the shears into the initial position. The basic speed is established by determining the feed rate of the material to be cut and is conveniently stored, but can also be determined, for example, by transducers which are coupled to the rolls of drivers, stands or the like. <IMAGE>

Patent DE-3708538-A1 (DE)
Title: Oscillator circuit
Inventor: FISCHER HELMUT DIPL ING
IPC: H03L7/23
Filed: 1987-03-13
Abstract: In an oscillator circuit having an output oscillator in a phase-locked loop, certain problems occur in achieving a high adjustment accuracy of the desired frequency because the influence of the characteristic of the voltage-control oscillators in a circuit driving a phase discriminator in the phase-locked loop is included in the frequency adjustment. To obtain an oscillator circuit with faster and more accurate adjustment of the frequency in each case desired, a difference frequency measuring arrangement (26) with a counter (33) is provided which, on the one hand, is connected to the output (13) of a voltage-controlled reference frequency oscillator (14) and, on the other hand, to the output of a frequency standard (29). The difference frequency measuring arrangement (26) is followed by a computer (22), one output (21) of which is connected to a digital/analog converter which precedes the reference frequency oscillator (14). The computer (22) contains a further output (22) for coarse adjustment, which is connected to a frequency divider circuit (5) in the phase-locked loop (1), and an input input (36) for selecting the respective frequency. The oscillator circuit provides for accurate and fast adjustment of frequencies with relatively little circuit complexity. <IMAGE>

Patent DE-3719816-A1 (DE)
Title: Method of producing helical compression springs
Inventor: ECKHARDT MARTIN DIPL ING
IPC: B23K26/364
Filed: 1987-06-13
Abstract: Such springs were separated from the trailing wire or from the next spring by complicated mechanical cutting and were ground in a relatively complicated manner at their ends until approximately plane-parallel end faces at right angles to the spring axis were produced, in the course of which length and form errors of the spring occurred which called for larger tolerances. The main object has therefore been to improve the production by simplification, by permitting smaller tolerances and by shortening the time. Use of a preferably flat laser beam for cutting through the spring wire and/or for producing, if need be simultaneously, the end faces at the spring ends. The production method using a laser beam producing the end faces can be carried out quickly, requires no grinding device, protects the structure of the wire material of the end faces at the spring ends as well as the environment, and permits simple material recovery as sublimate as well as scrap. The production method using a laser beam cutting through the wire makes a mechanical cutting device unnecessary and helps to achieve burr-free end faces at the spring ends.
